Sleep support
Why Deep Sleep is the best preset to start with
Sleep is the easiest repeat use case for binaural beats, which makes Deep Sleep the strongest starting point for new listeners.
Built for nightly use
The app makes the most sense when it becomes part of a bedtime routine instead of a one-off experiment.
Low-friction first session
Deep Sleep gives new users a calm starting point without learning the whole catalog first.
Consistency is visible
Sessions, streaks, and completion history make it easier to see whether your wind-down routine is sticking.

Stereo headphones
Use stereo headphones, keep volume low, dim the room, and let the session run while you settle into bed.
This app supports routines and relaxation. It is not a medical treatment for insomnia or anxiety.
FAQ
Common questions before you start
Do I need headphones for binaural beats?
Yes. Binaural beats depend on separate left and right tones, so stereo headphones are the clearest way to hear the effect.
Which preset should I start with for sleep?
Deep Sleep (3 Hz) is a good first preset if your goal is wind-down or nighttime listening.
How long should a session be?
Start with 20 to 40 minutes. For bedtime use, lower volume and consistency usually matter more than pushing longer sessions.
Can I use it for focus too?
Yes. Try Focus or Calm Focus during study or work sessions.
